What are the potential effects of global warming in terms of climate change and how can they be arrested?

Global warming is currently is a rising issue in world wide.It is actually caused by human being itself.Factories and cars have release all the dangerous gaseous into the atmosphere for the past decades. This caused the temperature to raise between 0.6°C and 0.9°C for the past century.Besides rising in temperature there are also other consequences caused by the global warming.
One of it is the melting of ice caps and glasier.This is due to the high temperature.When the ice melt it will lead to the rising of sea level.This will cause flood to occur more frequent at the coastal area.This is very dangerous as almost 10 percent of the world population lived in coastal areas less than 10 meter above the sea level.The rate of melting of the ice is predicted to be higher every year as the temperature kept rising.This will cause the sea level to raise faster.Flood also occur as a result from the storm raining that kept falling.
According to “Al Gore 2000” global warming not only caused flood,it also caused drought to the neighbouring places. This happen cause global warming not only causing the increasing in precipitation but also relocate the precipitation.The worse continent that faces drought due to the relocation is Africa.There is lack of rainfall in Africa because it was relocate by the global warming.One of the biggest lake in Africa which is Chad had dried to almost nothing.And this makes the lives of the African more difficult.
Next,global warming also putting pressure in ecosystems.For instance growing season in whole world have been shifted by the warmer temperature.The growing season have become longer,and thus the plants need more water or otherwise it will dried up and risk causing fire.Most of the species will migrate to the poles as the temperature at their original places are not suitable for them anymore.Species that cannot migrate will face extinction. The IPCC estimates that 20-30 percent of plant and animal species will be at risk of extinction if temperatures climb more than 1.5° to 2.5°C.
Also many infectious disease may spread.Some city were build just above the mosquito line.But because of the global warming,the line have rise and caused the city were attacked by the mosquitoes.Not only mosquito but there were many types of other vector were manage to live as the they were actually killed by the winter but the shortening of winter have caused them to live.In the last quarter century,almost 30 new diseases were found.All this were actually caused by the global warming.
In the sea,the sea coral is bleaching.Many types of fishes and other seas animal depends on this coral for food.If the coral bleach,the fish species will extinct.This will also caused imbalance in the seas ecosystem.
There is a many ways mankind can help reducing the global warming.For example use more efficient electric appliances,use renewable source of energy and car pooling.All this may reduce the global warming by small percentage when only one human did but if everyone did it,it can reduce the carbon emission level by quite large percentage.(Al Gore 2000.)

  1. the introductory sentences are well written and easy to understand.all of the paragraphs have sufficient supporting details and examples except in the last paragraph, the points given are not sufficiently supported. there are no grammatical or spelling mistakes :)
